If they're going to end on some kind of anthem rock song, then the only other I think they have in their catalog is GSRnR, and I'm sure many of you will disagree, but I really don't care for that song.
'Paid to Think' and others don't have that strength of ending on something that is an anthem.
The good thing about Thursday is that it signals the end or near end of the show, does leave room for changes each time it's played (my favorite part is how Rollum changes up the drums during the last 'change my walk and my talk and my hair'), and it leaves a strong impression on first timers with a very climactic ending (I also like the vocal end that Roger used to put on it).
I can't grow a beard, and I don't like to party.
